Les rongeurs des niveaux solutréensde la grotte Rochefort (Saint-Pierre-sur-Erve, Mayenne, France) : un référentiel inédit pour le dernier maximum glaciaire du nord-ouest de la France
Quaternaire, 2018Co-Authors: Hanquet Constance, Desclaux Emmanuel, Hinguant StéphanAbstract:Le tamisage et le tri systématique des sédiments issus des niveaux solutréens de la grotte Rochefort ont permis de récolter de nombreux éléments anatomiques de rongeurs se rapportant à sept espèces. L’étude taphonomique permet de suggérer un apport exogène, lié à des rapaces nocturnes de taille moyenne et peu destructeurs (Bubo scandiacus, Strix nebulosa ou Asio otus). Du fait de leurs régimes alimentaires, ces prédateurs ne sont pas susceptibles d’avoir induit un important biais de représentation. La forte proportion de Microtus gregalis et de Dicrostonyx torquatus, en association – dans une moindre mesure – avec Spermophilus sp., confirme clairement l’existence de conditions climatiques très rigoureuses et indique la présence d’un biotope de type steppique. Les associations de rongeurs permettent par conséquent d’attribuer les niveaux étudiés au MIS 2, et plus particulièrement au Dernier Maximum Glaciaire (LGM), ce qui est en accord avec les datations radiométriques. En outre, la présence d’espèces inféodées à des biotopes relativement humides (Microtus agrestis, Arvicola sapidus et Arvicola amphibius) suggère la persistance d’un environnement humide et relativement boisé à proximité de la cavité et permet de penser que la vallée de l’Erve a joué le rôle de micro-refuge cryptique au cours du Dernier Maximum Glaciaire.Systematic sieving of sediments from the Solutrean levels of Rochefort cave provided many rodent remains referred to seven species. The taphonomic study suggests an accumulation of the remains by medium sized and little destructive nocturnal raptors (Bubo scandiacus, Strix nebulosa or Asio otus). Because of their particular prey preferences, these predators are not likely to have induced an important bias on the representation of species. The high proportions of Microtus gregalis and Dicrostonyx torquatus, in association with the occurrence of Spermophilus sp. to a lesser extent, clearly confirm the existence of very severe weather conditions and indicate the presence of a steppe biotope. The associations of rodents therefore support the assignment of the studied levels to MIS 2, especially at the Last Glacial Maximum (LGM), which is consistent with radiometric dating. Furthermore, the presence of rodent species closely related to moist habitats (Microtus agrestis, Arvicola sapidus and Arvicola amphibius) suggests that wet and wooded environments persisted next to the cavity and that the Erve Valley presumably was a micro-cryptic refugia during the Last Glacial Maximum

The intestinal nematode Trichuris Arvicolae affects the fecundity of its host, the common vole, Microtus arvalis
Parasitology Research, 2007Co-Authors: Julie Deter, Jean-francois Cosson, Yannick Chaval, Nathalie Charbonnel, Serge MorandAbstract:Parasites have detrimental effects on host fitness. Consequently, they play a major role for host population dynamics. In this study, we investigated experimentally the impact of the nematode Trichuris Arvicolae on the reproduction of its host, the common vole Microtus arvalis. Wild common voles were trapped in east of France and reared in standardized conditions before being experimentally infected. Infection with Trichuris Arvicolae did not affect host consumption of food or water. Parasitized females gave birth to slightly less pups (mean 3.36 ± 0.38) than unparasitized females (mean 3.60 ± 0.40). Controlling for natal litter size using analysis of covariance (ANCOVA), T. Arvicolae infection had a significant effect on the individual mass at birth, with pups from parasitized females having significantly lower mass (2.11 g ± 0.01) than pups from unparasitized females (2.20 g ± 0.01). Other measures of host reproductive outputs (time to first reproduction, mass of pups at weaning, litter survival) were not affected by maternal parasite infection. We discuss how these changes in M. arvalis reproductive investments associated with T. Arvicolae infection must now be investigated in the context of physiological trade-offs

genetic and morphological heterogeneity in small rodent whipworms in southwestern europe characterization of trichuris muris and description of trichuris Arvicolae n sp nematoda trichuridae
Journal of Parasitology, 2000Co-Authors: Carlos Feliu, Serge Morand, Marta Spakulova, Juan Carlos Casanova, Francois Renaud, Jean Pierrem Hugot, Francis Santalla, Patrick DurandAbstract:Genetic and morphological variability of whipworms Trichuris Roederer, 1761 (Nematoda: Trichuridae), parasites of small rodents in southwestern Europe, was studied. Isozyme patterns of natural populations of nematodes parasitizing rodent species of the Muridae (Apodemus sylvaticus, Apodemus flavicollis, Mus musculus) and Arvicolidae (Clethrionomys glareolus, Microtus agrestis, Microtus arvalis) were analyzed at 6 putative loci. Two diagnostic loci were found in T. muris from Muridae and from Arvicolidae. Thus, the existence of 2 species of Trichuris restricted to different host families was indicated. They included Trichuris muris Schrank, 1788, originally described as being from mice, and Trichuris Arvicolae n. sp., parasitizing the above species of Arvicolidae. The morphological variability of both species was compared. Although ranges of all morphological characters of the new species overlapped with those of T. muris, stepwise discriminant analysis yielded a 100% accurate classification of females when using vagina length and egg size. Males of T. muris and T. Arvicolae cannot be separated entirely. A set of 6 variables yielded 95.7% discrimination; the most discriminating variables were spicule size and body width.

Spread Parameters of the Borer Xylotrechus Arvicola (Olivier) (Coleoptera: Cerambycidae) in a 'Tempranillo' Vineyard in La Rioja (Spain): a Long-Term Study
'EDP Sciences', 2020Co-Authors: Ocete Rafael, Armendariz Ignacio, Ocete, Carlos Alvar, Maistrello Lara, Valle Melón, José Manuel, Rodríguez Miranda Álvaro, Usategui Frías LeireAbstract:Xylotrechus Arvicola (Olivier) (Coleoptera: Cerambycidae) is a polyphagous xylophagous beetle that is becoming a pest of increasing importance for vineyards in Spain, also because of the wood fungi developing in the galleries excavated by its larvae, which cause a progressive decline of the affected grapevines, until death. Between 1993 and 2015, a survey of the infestation caused by X. Arvicola and the symptoms caused by pathogenic wood fungi was performed in a 'Tempranillo' variety vineyard in La Rioja region (Spain). Maps showing the overtime spread of the borer and the diffusion of symptoms of grapevine decline and Eutypa dieback were obtained. Results indicated that the borer colonization began in the centre of the plot, followed by the first symptoms caused by the wood fungi a few years later. The statistical analysis showed that the evolution of infestation is characterized by a linear increase of new holes whereas the pattern of their allocation in the vines follows a bimodal distribution which, to some extent, can be simulated by a Poisson's model. Based on these observations, a methodology to estimate the state of the infestation over time is proposed. The procedure - based on a linear regression of the average number of holes per vine over a set of years - can be applied in a relatively simple way and provides the probability for a grapevine to have a certain number of exit holes in a definite year with a mean error of around 5

Identification of potential chemosignals in the European water vole Arvicola terrestris
Scientific Reports, 2019Co-Authors: Patricia Nagnan-le Meillour, Amandine Descamps, Chrystelle Le Danvic, Maurane Grandmougin, Jean-michel Saliou, Christophe Klopp, Marine Milhes, Coralie Bompard, Didier Chesneau, Kévin PoissenotAbstract:The water vole Arvicola terrestris is endemic to Europe where its outbreak generates severe economic losses for farmers. Our project aimed at characterising putative chemical signals used by this species, to develop new sustainable methods for population control that could also be used for this species protection in Great Britain. The water vole, as well as other rodents, uses specific urination sites as territorial and sex pheromone markers, still unidentified. Lateral scent glands and urine samples were collected from wild males and females caught in the field, at different periods of the year. Their volatile composition was analysed for each individual and not on pooled samples, revealing a specific profile of flank glands in October and a specific profile of urinary volatiles in July. The urinary protein content appeared more contrasted as males secrete higher levels of a lipocalin than females, whenever the trapping period. We named this protein arvicolin. Male and female liver transcript sequencing did not identify any expression of other odorant-binding protein sequence. This work demonstrates that even in absence of genome, identification of chemical signals from wild animals is possible and could be helpful in strategies of species control and protection.
